In planning this photo history we set out to record the story of Apollo before the colors fade and memories blur. At first we aimed to restrict ourselves to the actual expeditions to the Moon. But it soon became clear that this approach could not capture the scope and spirit of so far-reaching an enterprise. So we decided that the breadth of Apollo would be shown best from the differing perspectives of the people directly concerned. Each chapter author was encouraged to recount his part of the story as he remembered it. We refrained from homogenizing these contributions, although we recognized that they are necessarily personalized and slightly duplicative. But they do offer the viewpoints of some of the people who made Apollo happen, and thus may provide fresh insights into that incredible project.
